Can you show me the right wat it is done.
using binomial theorem: (x+8)^3
i did:
x^3+x^2(8)+x(8)^2+(8)^3... then im stuck finding how to get the number before each term

It's Pascal's triangle.
For a square the numbers in front are 1, 2, 1.
For a cube, the numbers in front are 1, 3, 3, 1
For the fourth power, the numbers are 1, 4, 6, 4, 1

You get the No. from the Pascal's Triangle. In this case, it would be: 1,3,3,1 and the final answer would be:
x^3 + 24x^2 + 192x +512

(x+8)^3
= 3C3x^3 + 3C2x^2(8) + 3C1x(8^2) + 3C0(8^3)
= x^3 + 24x^2 + 192x + 512

i think of you're on the the main suitable option music. Your answer is right yet you are able to simplify via removing the main suitable person-friendly denominator, which happens to be 3. so which you would be able to simplify your answer to right here. 3(4x^5-5x^4-3x^3+7)
